VM Freeze while copying within shared folder

[Nick Hemsley]

I am using ubuntu 8.04, running Vista as a guest OS. I am getting freezes when attempting to compile a .net project using nant.

I have narrowed it down to copying the file Nullables.Nhibernate.pdb (which I will attach), from one part of the shared filesystem to another.

This bug seems to be related to ​http://www.virtualbox.org/ticket/2055. However, neither 2.0.2 or the attached vboxsf.sys work.

I have attached 2 log files, one for the 2.0.2 version of vboxsf.sys (vbox.log), which causes a Guru Meditation, and one with the vboxsf.sys attached in ticket 2055 (Vbox.log.crash-with-trac-vbox.sys-file) which just freezed the system and causes video corruption.

I will attached the file that causes this bug, Nullables.Nhibernate.pdb.

Also, this bug only happens when I am using the copy, or xcopy command (also nant's copy). Copying with Explorer does not seem to excercise this bug.

Actually, *sigh*

It only happens reliably when I xcopy from the directory.

I will attach the minimum number of files that cause this problem. The following command causes problem:

xcopy /e files temp

Thanks for your detailed report and a good testcase. The problem has been reproduced. The attached driver fixes the crash here. Please test it and let me know whether it works for you.

Should be fixed in 2.0.6.
